Hi
Welcome to the MedHelp forum!
No, IBS can cause pain under right ribcage. However so can liver, gall bladder and pancreas problems. Duodenal ulcer too can cause pain under right ribcage. Hence get this diagnosed again by running tests to rule out these conditions.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
Have you been under any additional stress lately? Have you been eating any differently? Do you have any other symptoms besides mild pain under right rib cage?
not necarsserily,it does not have to be a severe attack,you could just have trapped wind on this occassioni was like it all day yesterday come the evening i was burping for about an hour and pains have gone
